描述了珠海机场航班显示系统──ＬＥＤ的多媒体系统网络结构，具体说明了所使用的ＡＴ＆Ｔ结构化布线系统，讨论了系统中采用的多媒体技术。重点分析了ＪＰＥＧ静止图像数据压缩技术，较深入地阐述了基于离散余弦变换（ＤＣＴ）的有失真压缩编码．目前，珠海机场的ＬＥＤ多媒体网络系统已投入实际使用，肩负着机场航班显示、文字广告、视频广告、动画广告等信息的播放和制作。
Describes Zhuhai Airport flight display system ─ ─ LED multimedia system network structure, specifies the AT & T structured cabling system used to discuss the system used in multimedia technology. Focusing on JPEG still image data compression technology, a more in-depth description of discrete cosine transform (DCT) based on the distortion of the compressed encoding. At present, Zhuhai Airport LED multimedia network system has been put into practical use, shoulder the airport flight display, text ads, video ads, animated ads and other information playback and production.
